To allwhom it may concern:

. Be a known that 1,-JmaLD-Wy a citizen of the United; 'States,.;residingat ctroit, in the county of .layne and State of Michigan, have invented. certain new and useful Improvements. in Valves, of which the following is a specification.

Thls invention relates to a valve, and more particularly to an arrangement thereof which obviates the necessity-of packing of the likearound the valve'stem'.

The invention consists in the matters 'hereinafter set forth, and more particularly pointed out the accompanying drawings,

The'drawing is'a view in central, longitud1nn l='.sect1on of a valve that embodies features of the invention.

Referring, thereto, a, substantially cylindrical casing, fitted 'at-each end for connection with piping is divided by a cross wall or diaphragm 2 in which there is an apertured valve seat 3 in substantially axial alinement with a lateral nipple 4 on the casing. A-bonnet 5 has an annular body 6 exteriorly screwthreadal to engage interior threads in thenipple 4 and an outer flange 7 that is seated on theouter face of the ni ple; A. stern 8 that is rotatable in a gui e aperture in the bonnet. smaller than the internal diameter of the body 6, has a flange or head tion the inner end; A collar 10 thatr is exteriorly screwthreaded to engage intehead 15 fixed thereon, andretained in the closure by a spring. 16 sufficient play being given the closure to allow the latter to center itself on the seat 3 readil The post engages an axial, screwthrea ed socket in the lower portion of the stem 8. A spiral 17 encircles the post with one end spring entering a recess 18 in the collar 10 and the other enga ing a recess 19 in the disk or head 15 an is in compression between these parts. The spring serves to prevent the post turning with the stem when the latter is retated as bya suitable hand wheel 20, wrench or the like. z

l operatioir wheu the valve is, opened, any liquid to escape must pass througlithe .threads' of-the post androf the collar and then around the joint made by; the. head 0 seated on the face in the body recess. and. past the stem which has good. turiiin'g fit in the guide aperture of thebody. Similarly, when closed,-these same obstacles are encountered, and furthermore, the stem. is

pressed outwardly and firmly against the underside of the bonnet by its pressure on the seat. There is no packing to deteriorate, or

to Y vitiate the fluid passing through the Obviously, changes in 'the details of construction may be made without departing from the spirit of the invention and I do notcare to limit myself'to any particular form or.- arrangement of parts. .i

lVhat I claim as my invention is-:-- I 1. A valve comprising a substantially cyllmlricalcasmg divlded internally by a d1a-.

phragm having a valve-south lateral nipple on the gusing in substantially axial alinement with the seat, a. bonnet having a lide aperture and an annular body detac ably secured in the nipple, a stem rotatable in the guide aperture in the bonnet having a flange on its inner end bearing against the under side of the bonnet Within the body and an axial socket in its lower end a collar detach ably secured on the body tor retaining the stem, a post havin screwthreaded engagement with the axia socket in the inner portion of thestem, a cupshaped closure rota table and oscillatory on the end of the post, and a spring encircling the post between the closure and the collar and interlocking with the collar and the post at its ends.

2. A valve comprisin a substantially c lindrical casing, a diap ragni dividing t e casing and having a' valve-seat, a lateral nipple on the casing in substantially axial guide aperture and an annular body in screwthreaded engagement with the nipple,a stem rota table in the guide aperture in the bonnet having an axial socket in its-lower end, a flange on the inner end of the stem, 9. etc

collar in screwthreaded' enga ement wit the body holding the stem ange seated against, the undersidelof the bonnet in the body, a washer interposed between the C01- lar and stem, a post having screwthreaded J1 engagement with the axial socket in the in-. ner portion of the stem, at cup-shaped closure I rotatable and oscillatory on the' end of the post, and a spring encircling the post be- 7.

lindrical casing divided internally bya diaphrag'm having a valve seat, a lateral ni ple on the casing in substantially axiala inement with the seat, a bonnet having a guide aperture and an annular body detachably secured in the nipple, a stem rotatable inthe guide aperture in the bonnet having an axial socket in its inner end and a flange on its inner end bearing against the underside of the bonnet within the body, collar detachably secured on the body for retaining the stem, a post having serewthreadedengagement'with the axial socket in the inner portion of the stem, a disk secured to the end of the post, a cup-shaped closure for the seat retaining the closure loosely on the disk, and a spiral spring encircling the post with its ends entering recesses in the adjacent faces i of the disk and cdllar.

' 4:. A valve comprisin a substantially cylindrical casing, a diap ragni dividing the' casing and having a valve-seat, a lateral nipthreaded engagement with the nipple, a stem 4 rotatable in the guide aperture in the bonnet having an axial socket in its inner end, a

flange on the inner end of the stem, at stop collar in scrcwthreaded. engagement with the body holding the stem flange seated against the undersidebfi the bonnet in the body, a washer interposed between the collarand stein, a post havingscrewthreaded engagement-with the; axial socket in the inner portion 'bf the stem, :1 disk secured to the endof the post, a cup-shaped closure for the seat rotatable'and oscillatory on the disk, aring retainingthe closure loosely on the disk, and aspiral spring encircling-the post with its endsexitring'reeesses in the adja-- "cent facesofthe disk-and collar. rotatable and oscillatory on the disk, a ring In testimony whereof I atiix my signature, in presence" of two witnesses.
